For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

1. NR SL resource allocation or selection

There are two ways of NR SL resource allocation, one based on network side device (e.g., base station) scheduling, mode1 (mode 1), and the other based on UE autonomous resource selection, mode 2 (mode 2). For mode1, the sidelink resource used for data transmission by the UE is determined by the base station and is informed to the sending UE (TX UE) through the downlink signaling, for the resource allocation mode selected by the UE independently, the UE selects available transmission resources in a preconfigured or configured resource pool, the UE firstly monitors a channel (sending) before the resource selection, selects a resource set with smaller interference according to the channel monitoring result, and then randomly selects the resource used for transmission from the resource set. For mode 2, the specific operation is as follows:

1) After the resource selection is triggered, the TX UE first determines a resource selection window, where the lower boundary of the resource selection window is at a time T1 after the triggering of the resource selection, and the upper boundary of the resource selection is at a time T2 after the triggering, where T2 is a value selected by the UE within a packet delay Budget (PACKET DELAY bridge, PDB) transmitted by a Transport Block (TB), and T2 is not earlier than T1.

2) Before the UE selects a resource, it needs to determine an alternative resource set (CANDIDATE RESOURCE SET) for the resource selection, and compares the reference signal received Power (REFERENCE SIGNAL RECEIVING Power, RSRP) measured on the resource within the resource selection window with a corresponding RSRP threshold (threshold), and if the RSRP measured on a certain resource is higher than RSRP threhold, the resource is excluded and the alternative resource set cannot be included. And after the resource is removed, the remaining resources in the resource selection window form an alternative resource set. The ratio of the resources in the alternative resource set to the resources in the resource selection window is not less than x%, wherein x% may be a value configured or preconfigured by the control node, if less than x%, RSRP threshold needs to be increased according to a step value (3 dB), and then the resource exclusion operation is performed until the resources not less than x% may be selected.

3) After the alternative resource set is determined, the UE randomly selects transmission resources in the alternative resource set. In addition, the UE may reserve transmission resources for the next transmission at this time of transmission.

2. Downlink (DL)/uplink (Up Link, UL) beam indication

In the fifteenth version (Release 15, rel-15) NR Uu, the beam can be set independently for a certain transceiving operation of the UE. The transceiving beam of the physical downlink control channel (Physical Downlink Control Channel, PDCCH)/physical uplink control channel (Physical Uplink Control Channel, PUCCH) may be preconfigured, and the transceiving beam of the PDSCH/PUSCH may be semi-statically configured or dynamically indicated by control information.

In seventeenth version (Release 17, rel-17) NR Uu, for a UE to transmit and receive in a certain scheduled time period, the UE uses an indicated Unified Beam (Unified Beam) for transmitting and receiving.

The beam processing method provided by the embodiment of the application is described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a beam processing method according to an embodiment of the present application, including the following steps:

Step 201, a first terminal sends a first beam indication to a second terminal;

In this embodiment, one of the first terminal and the second terminal may be a transmitting terminal (TX UE) and the other may be a receiving terminal (RX UE). The at least one beam may be a receive beam, or may be a transmit beam, or may be a recommended receive beam, or may be a recommended transmit beam, etc. Each of the at least one beam pair (beam pair) includes a transmit beam and a receive beam. The resources associated with the at least one beam or beam pair may include at least one of time domain resources, frequency domain resources, resource pools, and the like. It will be appreciated that the present embodiment may support maintaining multiple pairs of beams between a first terminal and a second terminal, e.g., between a TX UE and an RX UE as shown in fig. 3.

The first terminal may send the first beam indication to the second terminal, for example, in a semi-static manner or in a periodic manner, e.g., the first terminal may send the first beam indication to the second terminal via higher layer signaling (e.g., PC5 radio resource control (Radio Resource Control, RRC)), or the first terminal may send the first beam indication to the second terminal in a dynamic or non-periodic manner, e.g., the first terminal may send the first beam indication to the second terminal via dynamic signaling (e.g., medium access control element (MEDIA ACCESS Control Control Element, MAC CE) or sidelink control information (Sidelink Control Information, SCI), etc.), or the first terminal may send the first beam indication to the second terminal in a semi-persistent manner, e.g., the first terminal may further activate or deactivate the configured first beam indication via dynamic signaling (e.g., MAC CE or SCI, etc.).

It should be noted that the number of the first beam indicators may be one or at least two. For example, in the case that the first terminal indicates a beam to the second terminal through higher layer signaling, the first terminal may send a beam configuration to the second terminal through higher layer signaling, where the beam configuration may include at least two first beam indications, and further, the first terminal may activate or deactivate the first beam indication in the beam configuration through dynamic signaling.

In an example, after the first terminal sends the first beam indication to the second terminal, the first terminal and the second terminal may determine a transmission beam based on the first beam indication, taking the first terminal as a transmitting terminal and the second terminal as a receiving terminal as an example, where the first beam indication indicates a beam pair, the first terminal may send data based on the transmission beam in the beam pair, and correspondingly, the second terminal may receive data based on the reception beam in the beam pair, where the first beam indication indicates a reception beam, the first terminal may determine a transmission beam to send data based on the reception beam indicated by the first beam indication, and correspondingly, the second terminal may receive data based on the reception beam indicated by the first beam indication, and where the first beam indication indicates a resource, the first terminal may send data based on the transmission beam associated with the resource indicated by the first beam indication, and the second terminal may receive data based on the reception beam associated with the resource indicated by the first beam indication.

The beam processing method provided by the embodiment of the application comprises the steps that a first terminal sends a first beam indication to a second terminal, wherein the first beam indication is used for indicating at least one of at least one beam or at least one beam pair, at least one beam associated resource or at least one beam pair associated resource, and because the first beam indication is sent to the second terminal by the first terminal, the first terminal and the second terminal can align transmission beams based on the first beam indication in the SL transmission process, and further the SL transmission reliability between the first terminal and the second terminal can be improved.

Optionally, the first beam indication comprises at least one of beam information for indicating at least one beam or at least one beam pair, and resource information for indicating at least one beam-associated resource or at least one beam pair-associated resource.

In this embodiment, the beam information may include, but is not limited to, at least one of beam identification (beam ID), beam pair identification (beam pair ID), resource identification (resource ID), transmission configuration indication (Transmission Configuration Indication, TCI), beam repetition (beam repetition), and beam scanning (beam sweeping).

The resource information may include, but is not limited to, time domain resource information, frequency domain resource information, and resource pool information.

Wherein, the time domain resource information may include, but is not limited to, at least one of the following:

A resource start position, for example, an Offset (Offset) of a slot (slot) or a symbol (symbol), an Offset of an absolute time (absolute time), a slot Offset and a symbol Offset, or the like;

a resource length (Duration), e.g., a slot length (Duration in slot), or a symbol length (Duration in symbol) or an absolute time length (Duration in absolute time);

Resource Period (Period);

reference subcarrier spacing (Subcarrier Spacing, SCS).

In some alternative embodiments, the time domain resource information may be time domain resource information associated with beam information.

The time domain resource Information may include a time domain resource corresponding to a signal or a Channel, a symbol of a Physical Sidelink Control Channel (PSCCH), a symbol of a physical sidelink shared Channel (PHYSICAL SIDELINK SHARED CHANNEL, PSSCH), a symbol of a PSSCH and an automatic gain Control (Automatic Gain Control, AGC), a symbol of an independent networking (SA) Channel state Information reference signal (CHANNEL STATE Information REFERENCE SIGNAL, CSI-RS), a symbol of an SA CSI-RS and an AGC, a symbol of a physical sidelink Feedback Channel (PHYSICAL SIDELINK Feedback Channel, PSFCH), a symbol of PSFCH and an AGC, and the like.

The above frequency domain resource information may include, but is not limited to, at least one of carrier index (carrier index), bandwidth part index (BWP index), and the like. The resource pool information may include, for example, a pool identification (pool ID).

In some optional embodiments, each beam indication may include at least one of a plurality of time domain resource information and a plurality of beam information, e.g., the UE may be instructed to perform beam scanning (beam sweeping) operations with different beams on the plurality of time domain resources.

Optionally, the first beam indication further comprises at least one of:

an indication identifier of the first beam indication;

Channel measurement information for channel measurement between the first terminal and the second terminal;

position information of the first terminal;

Propagation type information.

In this embodiment, different beam indicators may correspond to different indication identifiers (e.g., numbers), so that in the case where there are multiple beam indicators, the different beam indicators may be distinguished based on the indication identifiers. For example, in the case that the first terminal needs to update the beam information, the time domain resource information, and the like included in a certain beam indication, the indication information may be sent to the second terminal, where the indication information may carry an indication identifier of the beam indication, so that the second terminal determines, based on the indication identifier, the beam indication that needs to be updated.

The channel measurement information may include parameters reflecting channel quality and channel characteristics, such as RSRP values, channel quality indication (Channel Quality Indicator, CQI) values, recommended modulation coding scheme (Modulation and Coding Scheme, MCS) values, and the like. For example, for a beam indication sent by an RX UE, the RX UE may simultaneously carry channel measurement information in the beam indication, which may be measurement information for a certain transmit beam (TX beam) or for a beam pair of a certain TX beam and a receive beam (RX beam).

In some alternative embodiments, the channel measurement information may reflect large-scale fading information, long-term (long term) RSRP/Layer 3 (Layer 3, l 3) filtered (filtered) RSRP, which is used to assist the TX UE in power control and other operations.

In some alternative embodiments, the above-mentioned channel measurement information may have a timeliness, where the timeliness may be preset, or the timeliness is indicated by the indication signaling, or an end time of the timeliness is when the indication signaling for updating the channel measurement information is received. Optionally, the first beam indication further includes an effective time of the channel measurement information, and the channel measurement information is effective during the effective time.

The geographical location information of the first terminal, for example, a zone ID. For example, beam information may be indicated along with location information (e.g., zone ID). The region may indicate the approximate location of the TX UE, and then the RX UE may infer the relative location and direction (e.g., north-east or south-west) between the UEs from its own region and the region of the TX UE. If the beam information is a global direction indication (e.g., southwest, northwest), then the zone ID in combination with the beam information (e.g., beam ID) the RX UE may infer whether the TX UE's transmissions would send collisions, interference, etc.

The broadcast type (Cast type) information indicates a broadcast type, wherein the broadcast type may include unicast, multicast, broadcast, or the like. For example, different propagation types may have different beam indications. In some alternative embodiments, the propagation type may be determined by the source identification (source ID) or destination identification (destination ID) for which the beam indication is intended.

Optionally, the first beam indication is indicated by a semi-static manner or by a periodic manner.

For example, in case the first beam indication is indicated by a semi-static manner or by a periodic manner, the first terminal may transmit the first beam indication to the second terminal through the PC5 RRC.

Optionally, the method further comprises:

The first terminal sends a first indication signaling to the second terminal, wherein the first indication signaling comprises a first indication identifier and is used for indicating to release the beam indication identified by the first indication identifier.

In this embodiment, the first terminal may send an indication signaling to the second terminal to release the beam indication, for example, by indicating to the second terminal to release the beam indication through a specific indication field.

In this embodiment, different beam indicators are supported to be distinguished by the indication identifier, and the beam indicator identified by a certain indication identifier can be released by the indication signaling, so that the terminal can maintain multiple beams or multiple beam pairs simultaneously, so as to combat a channel which changes rapidly in a SL communication scene.

Optionally, the method may further include:

The first terminal sends update indication signaling to the second terminal, wherein the update indication signaling comprises first beam information for indicating to update the first beam indication according to the first beam information.

In this embodiment, the first beam information may include, but is not limited to, at least one of beam identification, beam pair identification, resource identification, TCI, beam repetition, and beam scanning.

In an exemplary embodiment, the second terminal may update the beam information indicated by the first beam to the first beam information when receiving the update indication signaling.

Optionally, the update indication signaling further includes a first target indication identifier, and the update indication signaling is used for indicating that the beam information of the beam indication identified by the first target indication identifier is updated to be the first beam information.

In this embodiment, the update indication signaling further includes a first target indication identifier, so that in a case where there are multiple beam indications, the second terminal may determine, based on the first target indication identifier, a beam indication that needs to be updated.

Optionally, the method further comprises:

The first terminal sends a second indication signaling to the second terminal, wherein the second indication signaling is used for indicating to activate or deactivate the first beam indication.

For example, in case the first terminal transmits the first beam indication to the second terminal in a semi-persistent manner, for example, the first terminal transmits at least one first beam indication to the second terminal through higher layer signaling, in which case the first terminal may activate or deactivate part or all of the at least one first beam indication through dynamic signaling, for example, the at least one first beam indication indicated through PC5 RRC through MAC CE or SCI or physical layer signaling, etc.

In some optional embodiments, the activation time of the first beam indication may be a preset time, or the activation time may be continued until the periodic beam indication corresponding to the indication identifier is deactivated, or the activation time may be continued until the new activation signaling is validated.

Optionally, the second indication signaling includes a second indication identifier, where the second indication signaling is used to indicate to activate or deactivate the first beam indication corresponding to the second indication identifier.

In this embodiment, the second indication identifier may include an indication identifier of at least one first beam indication.

In an exemplary embodiment, when the number of the first beam indicators is multiple, the first terminal carries the second indicator in the second indicator signaling to indicate to activate or deactivate the first beam indicator corresponding to the second indicator, so that signaling overhead can be saved.

Optionally, the first beam indication is indicated in a dynamic manner or in an aperiodic manner.

Illustratively, the first terminal may send the first beam indication to the second terminal through MAC CE or SCI or physical layer signaling.

Optionally, the first beam indication includes a resource identifier, where a resource identified by the resource identifier is a resource configured by the first terminal through higher layer signaling;

Or alternatively

The first beam indication comprises a third indication identifier, and the beam indication identified by the third indication identifier is configured by the first terminal through higher layer signaling.

For example, the resource information (e.g., time domain resource information) may be configured by higher layer signaling (e.g., PC 5-RRC), while the dynamic signaling only carries the identification (e.g., number) of the resource, or the time domain resource information and the beam information may be configured by higher layer signaling (e.g., PC 5-RRC), the dynamic signaling only indicates the configuration identification (e.g., number), i.e., at least one beam indication is configured by higher layer signaling, each beam indication includes the time domain resource information and the beam information, while the dynamic signaling only carries the indication identification of the beam indication, which may save the overhead of the dynamic signaling.

In some alternative embodiments, at least one of the plurality of time domain resource information and the plurality of beam information may be included in the dynamic signaling sent by the first terminal to the second terminal, such that the terminal may dynamically maintain a plurality of beam pairs at the same time, or the terminal may dynamically instruct beam scanning (beam sweeping) or the like.

Optionally, the method further comprises:

In case that a beam conflict exists between at least two beam indications at the same time is detected, the first terminal determines the effective beam indication according to the priority relation between the at least two beam indications.

In this embodiment, there is a beam conflict between at least two beam indications at the same time, which may be understood that the beams indicated by the at least two beam indications at different frequencies at the same time are different, for example, beam indication a indicates that the beam of carrier A1 at symbol a is beam A1, and beam indication B indicates that the beam of carrier B1 at symbol a is beam B1, where beam A1 and beam B1 are different beams.

The priority relation between the at least two beam indications may be predefined by a protocol, may be determined by a control node, may be determined based on the content of the at least two beam indications, etc., as examples.

The determining the effective beam indication according to the priority relation between the at least two beam indications may, for example, determine the beam indication with the highest priority among the at least two beam indications of the transmission beam conflict as the effective beam indication.

For example, in a case where the first terminal transmits a plurality of beam indicators to the second terminal, or in a case where the first terminal transmits a plurality of beam indicators to the plurality of second terminals, if there is a transmission beam conflict between the plurality of beam indicators, the first terminal may determine an effective beam indicator according to a priority relationship between the plurality of beam indicators transmitting the beam conflict.

Optionally, for the scenario in which the first terminal sends multiple beam indications to the second terminal, the second terminal may be a physical device or multiple logical UEs corresponding to the physical device, for example, a logical UE corresponding to a unicast identifier (unicastist ID), a logical UE corresponding to a multicast identifier (groupcast ID), or a logical UE corresponding to a broadcast identifier (broadcast ID). For the scenario that the first terminal sends multiple beam indications to multiple second terminals, the multiple second terminals may be understood as multiple logical UEs, and optionally, the multiple logical UEs may be multiple logical UEs corresponding to the same physical device.

Optionally, the priority of the beam indication indicated by the dynamic or non-periodic means is greater than the priority of the beam indication indicated by the semi-static or periodic means;

Or alternatively

The priority of beam indication by semi-static means or by periodic means is greater than the priority of beam indication by semi-persistent means;

Or alternatively

The priority of beam indications, which are indicated in a dynamic or non-periodic manner, is greater than the priority of beam indications, which are configured in a semi-persistent manner.

In this embodiment, the beam indication configured in the semi-persistent manner may be a beam indication configured through higher layer signaling, for example, PC5 RRC signaling.

Optionally, the priority relation between the at least two beam indications is determined according to at least one of the following information:

Priority indication information carried by at least one beam indication of the at least two beam indications;

An indication granularity of at least one of the at least two beam indications;

a transmit time of at least one of the at least two beam indications;

At least one beam indication of the at least two beam indications corresponds to a channel or signal;

At least one beam of the at least two beam indications indicates first information of a corresponding frequency domain resource, wherein the first information comprises at least one of a position, a sequence number and a type, and the type comprises a reference frequency domain resource or a non-reference frequency domain resource;

at least one of the at least two beam indications indicates a corresponding propagation type.

In this embodiment, the priority indication information carried by the beam indication is used to indicate the priority of the beam indication, for example, the priority indication information may be a priority identifier.

For determining the priority relation based on the priority indication information carried by the beam indications, in some alternative embodiments, each of the at least two beam indications carries priority indication information, such that the priority relation between the at least two beam indications may be determined based on the priority indication information carried by each of the at least two beam indications. In some alternative embodiments, if there is a partial beam indication carrying a priority identifier among the plurality of beam indications for which beam collision occurs, the partial beam indication does not carry a priority identifier, and the beam indication carrying the priority identifier has a higher priority than the beam indication not carrying the priority identifier. For example, if the beam indication of the periodic indication includes a priority identification, the beam indication of the periodic indication has a higher priority than the beam indication without the priority identification. For reference signal (REFERENCE SIGNAL, RS) transmission of radio link monitoring (Radio Link Monitor, RLM) with higher priority, the beam indication corresponding to the RS of the RLM may carry a priority identification.

For the indication granularity based on the beam indication, a priority relation is determined, for example, a priority of the beam indication with the symbol (symbol) as the indication granularity is higher than a priority of the beam indication with the slot (slot) as the indication granularity, so as to prioritize transmission of the RS. In some alternative embodiments, the priority relationship between at least two beam indications may be determined according to an indication granularity of each of the at least two beam indications.

For determining the priority relation based on the transmission time of the beam indication, for example, the priority of the beam indication with a later transmission time is higher than the priority of the beam indication with an earlier transmission time. Illustratively, after the beam indication at a later transmission time is validated, the UE adjusts the beam according to the beam indication. In some alternative embodiments, the priority relationship between at least two beam indications may be determined according to the transmission time of each of the at least two beam indications.

For determining the priority relation based on the channels or signals corresponding to the beam indications, for example, the priorities of various channels or signals can be agreed by a protocol so as to protect the transceiving of important signals. Illustratively, beam collision occurs between the beam indication corresponding to the CSI-RS and the beam indication corresponding to the PSCCH/PSSCH, the beam indication corresponding to the CSI-RS is preferentially validated, and the beam indication corresponding to the CSI-RS and the beam indication corresponding to PSFCH occur, the beam indication corresponding to PSFCH is preferentially validated. In some alternative embodiments, the priority relationship between at least two beam indications may be determined from each of the at least two beam indications corresponding to a channel or signal.

A priority relationship is determined for the first information indicating the corresponding frequency domain resources based on the beam, wherein the frequency domain resources may include, but are not limited to, a resource pool (pool), a carrier (carrier), or a BWP. The reference frequency domain resource, e.g., a reference resource pool (REFERENCE POOL), a reference carrier (REFERENCE CARRIER), or a reference BWP (reference BWP), the non-reference frequency domain resource is a frequency domain resource that is relative to, i.e., different from, the reference frequency domain resource. Illustratively, the lower the sequence number, the higher the priority of the beam indication corresponding to the frequency resource, or the higher the priority of the beam indication corresponding to the reference frequency domain resource than the non-reference frequency domain resource. In some alternative embodiments, the priority relationship between at least two beam indications may be determined from the first information of the corresponding frequency domain resource for each of the at least two beam indications.

A priority relationship is determined for the propagation type to which the beam indication corresponds, e.g. the beam indication corresponding to unicast has a higher priority than the beam indication corresponding to multicast or the beam indication corresponding to multicast has a higher priority than the beam indication corresponding to broadcast. In some alternative embodiments, the priority relationship between at least two beam indications may be determined according to a corresponding propagation type of each of the at least two beam indications.

Optionally, the priority of the second beam indication is greater than the priority of the third beam indication, where the second beam indication is a beam indication corresponding to a channel on a reserved resource or a signal on a reserved resource, and the third beam indication is a beam indication other than the second beam indication in the at least two beam indications.

In this embodiment, in the case where the priority relationship is determined according to the channel or signal corresponding to each of the at least two beam indicators, the priority of the beam indicator corresponding to the channel or signal on the reserved resource is higher than the priority of the beam indicators corresponding to the other signals or channels. The beam indication corresponding to the channel or the signal on the reserved resource may also be referred to as a beam indication corresponding to the real channel or the signal transceiving.

In some alternative embodiments, for beam collision of a real channel or signal transceiving (i.e. a channel or signal on a reserved resource), the processing manner may further include determining a priority of a beam indication according to the priority of the channel or signal, and sending at least one of the beam collision indication, the resource reselection indication, the retransmission indication, and the like to the opposite end.

For example, in a case where the second terminal receives a plurality of beam indications from a plurality of first terminals, the second terminal may transmit collision indication information or beam suggestion information to the first terminal in a case where it detects that there is a beam collision between at least two beam indications at the same time. In this scenario, the plurality of first terminals may be a plurality of logical UEs, and optionally, the plurality of logical UEs may be a plurality of logical UEs corresponding to the same physical device.

In another embodiment, in a case where the first terminal detects that there is a beam collision between at least two beam indications at the same time, the first terminal may send collision indication information or beam suggestion information to the second terminal, and the second terminal may perform collision processing based on the collision indication information or the beam suggestion information, for example, may determine a beam indication that is effective among at least two indication beams in which there is a beam collision according to the collision indication information, or determine a beam indication that is effective according to the beam suggestion information.

Optionally, the conflict indication information comprises at least one of indication identification of fourth beam indication, corresponding source identification of the fourth beam indication, corresponding destination identification of the fourth beam indication and beam conflict mark, wherein the fourth beam indication is beam indication of beam conflict.

The fourth beam indicates a corresponding source identifier (source ID) for indicating a terminal that transmits the fourth beam indication, and the fourth beam indicates a corresponding destination identifier (destination ID) for indicating a terminal that receives the fourth beam indication. The beam collision flag (flag) is used to indicate that a beam collision has occurred.

For example, in a case where there is a beam conflict between the beam indication sent by the first terminal and the beam indication received by the first terminal, the beam indication that is validated by default may be the beam indication sent by the first terminal, or the beam indication that is validated by default may be the beam indication received by the first terminal.

In the case of transmitting beam collision between a plurality of beam instructions, the transmitting terminal may be a logical UE or a physical UE (i.e., a physical device) from the transmitting side of the beam instructions, but the receiving terminal is generally referred to as a logical UE, or the transmitting terminal may be a physical UE corresponding to a plurality of logical UEs when acquiring a plurality of logical UE IDs (e.g., unique ID, groupcast ID, broadcast ID, etc.) corresponding to the receiving side. The receiving terminal may be a logical UE or a physical UE from the receiving side indicated by the beam, but the transmitting terminal may be a logical UE in general, or the receiving terminal may be a physical UE corresponding to a plurality of logical UEs when acquiring a plurality of logical UE IDs (e.g., unique ID, groupcast ID, broadcast ID, etc.) corresponding to the transmitting side.

It should be noted that, one of the beam instruction transmitted from the transmitting terminal to the receiving terminal and the beam instruction transmitted from the receiving terminal to the transmitting terminal is auxiliary information, and the collision processing of the auxiliary information may be performed by the terminal.

For example, when the base station schedules transmission of the TX UE to the RX UE, the base station preferentially schedules resources located on time domain resources reported by the TX UE. For another example, the base station determines the interference direction of the signal according to the beam direction of the beam indicated by the beam information reported by the TX UE, and schedules the transmission resource of the TX UE to other UEs according to the interference direction so as to implement space division multiplexing.
