Embodiments of the invention

Embodiments of the present invention will be described below with reference to the drawings and embodiments. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments in the present application may be arbitrarily combined with each other.

FIG. 1 is a schematic diagram of a wireless network architecture including a coordinated UE (first UE) and a benefit UE (second UE) according to an embodiment of the present invention. The cooperative UE communicates with the base station through the first link, and the first link may be an LTE link, a 5G link, a dual connectivity link, a LAA (Licensed-Assisted Access) link, and a tightly coupled chain. Road and so on. The benefiting UE communicates with the base station through the second link, which may be an LTE link, a 5G link, a dual connectivity link, an LAA link, a tightly coupled link, and the like. The coordinated UE and the benefiting UE communicate through the third link, which may be an LTE link, a 5G link, a dual connectivity link, a LAA link, a tightly coupled link, and the like. In general, it is assumed that the first link communication performance (e.g., available rate) and the third link communication performance are higher than the second link communication performance. Moreover, the communication performance of data forwarding through the first link and the third link is also higher than the second link communication performance. A typical example is that the first link (and the first UE) employs a more advanced but later marketed communication technology/protocol or has more abundant spectrum resources, a third link and a second link (and second UE) uses less backward but more morning communication technologies or protocols, or has less spectrum resources. On the other hand, the third link and the second link adopt the same communication protocol (adaptation to benefit the UE-capable communication protocol), but the communication distance of the third link is much smaller than the communication distance of the second link and is under the same base station. Communication between a plurality of third links that are far apart from each other (ie, between different cooperative UEs and the pair of benefiting UEs) is small, and multiple third links can reuse frequency resources, and thus the communication capacity of the third link is high. The communication capacity of the second link. The communication performance of data forwarding through the first link and the third link is also higher than the communication performance of the second link, so that the link of the data stream from the base station to the benefit UE can be offloaded to the base station to the coordinated UE and then to the chain of the benefit UE. road.

FIG. 2 is a schematic diagram of a wireless network topology including a coordinated UE and multiple benefit UEs according to an embodiment of the present invention. In a communication network, when a UE that uses more advanced communication technologies and protocols or can communicate using more abundant spectrum resources (referred to as a new UE) enters the market, it adopts a later communication technology and protocol or The number and density of UEs that can use fewer spectrum resources (referred to as old UEs) are much more than the number and density of new UEs, which makes the old spectrum very crowded and the usage of new spectrum very low. By offloading the data stream from the base station to the old UE's link to the new UE and then to the old UE's link (as shown in Figure 1), the throughput of the old UE can be significantly improved, and the old spectrum can be mitigated. Load, improve the quality of service of the old network.

Embodiment 1

FIG. 3 is a simplified flowchart of a unicast data transmission performed by a coordinated UE analog base station according to Embodiment 1 of the present invention. As shown in Figure 3, the following steps are included:

Step 301: The first UE receives configuration information of the base station.

Step 302: The first UE receives data to be sent to the second UE.

Step 303: The first UE simulates that the base station sends the data to the second UE according to the configuration information of the base station.

The method of the embodiment of the present invention is clarified in detail through a plurality of examples.

Example 1 (Beneficial UE is LTE R8/R9UE, ie Long Term Evolution version 8 or version 9 UE)

The reference signals corresponding to R8/R9 are reference signals such as Cell-specific reference signals (CRS), Sounding Reference Signal (SRS), De Modulation Reference Signal (DMRS), and reference signals. It exists between the eNB and the cooperative UE, the eNB and the beneficiary UE, and the cooperative UE and the benefit UE. Based on the RRC control plane information, there are two transmission modes. One is that all Radio Resource Control (RRC) control messages are transmitted between the eNB and the beneficiary UE and between the eNB and the coordinated UE. Participating in the forwarding of RRC control plane information; the other is the RRC control plane message between the eNB and the beneficiary UE, between the eNB and the coordinated UE, and between the cooperative UE and the benefit UE, and the cooperative UE participates in the forwarding of the RRC control plane information. This article mainly describes the user plane data transmission.

4 is a complete flowchart of a cooperative UE simulating base station service benefit UE according to Embodiment 1 of the present invention; as shown in FIG. 4, the method includes the following steps:

Step 401: The base station receives an authorization to authorize the coordinated UE to perform an analog base station to send a downlink signal of the cell. The authorization generally comes from the core network, such as the Mobility Management Entity (MME). The authorization information may also include an identification of the beneficiary UE that the cooperative UE can serve.

Step 402: The eNB configures the coordinated UE according to the capability of the benefiting UE and/or the capability of the coordinated UE. Sending a downlink reference signal to the benefit UE and/or configuring the coordinated UE to measure the SRS signal of the benefit UE, for example, the downlink reference signal may be a CRS, a channel state information reference signal (CSI-RS), a discovery reference signal (Discovery Reference Signal, DRS).

Step 403, according to step 402, at least one of the two options; option a (based on the measurement of the downlink reference signal sent by the coordinated UE):

Step 403a-1: The coordinated UE sends a downlink reference signal.

Step 403a-2: The benefit UE reports a Channel Quality Indicator (CQI) and/or a Reference Signal Receiving Power (RSRP) (Reference Signal Receiving Power) of the reference signal to the base station;

Option b (based on the measurement of the SRS of the benefiting UE):

Step 403b-1, the cooperative UE receives and measures the SRS sent by the benefiting UE;

Step 403b-2: The cooperative UE reports the SRS measurement result to the base station;

Step 404: The base station configures the coordinated UE to serve the benefit UE, where the configuration includes a bearer or a logical channel, and further includes a configuration of the scheduling aspect.

Step 405: The base station sends the downlink data of the benefit UE to the coordinated UE, and the coordinated UE receives the downlink data of the benefit UE.

Step 406: The coordinated UE sends the downlink data of the benefit UE to the benefit UE.

FIG. 5 is a schematic diagram of a transmission protocol stack between a base station, a coordinated UE, and a benefit UE according to Embodiment 1 of the present invention. As shown in FIG. 5, the processing of the Packet Data Convergence Protocol (PDCP) layer (including security and header compression) is performed between the base station and the benefit UE, and the coordinated UE does not participate in the PDCP layer processing, and the benefit is that the cooperative UE The data of the forwarded benefit UE is encrypted data, that is, the privacy of the benefiting UE is not exposed to the cooperative UE. The coordinated UE participates in Radio Link Control (RLC) layer/Media Access Control (MAC) layer/physical (physical) according to the configuration of the base station (step 404 of FIG. 4) to benefit the UE data transmission. Layer, PHY) layer processing, in which the RLC/MAC/PHY transmission from the base station to the beneficiary UE is divided into two segments. For the AM transmission mode, the transmission reliability is respectively determined by the automatic retransmission request of the two segments (Automatic Repeat reQuest , ARQ) / hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) process support. For the non-acknowledged mode UM transmission mode, the transmission reliability is supported by the two-stage HARQ process. For example, the downlink data is first reliably transmitted to the cooperative UE and then reliably transmitted to the benefit UE. When the downlink data arrives at the coordinated UE from the base station, the coordinated UE needs to distinguish the downlink data from itself or the UE, and the coordinated UE distinguishes the data of the one bearer according to the configuration of the base station (step 404 in FIG. 4). Whether the receiver is its own or the UE. For example, the base station may be configured to associate the (partial) bearer of the benefiting UE with the partial bearer of the coordinated UE, and the downlink data received by the coordinated UE through the bearer or the logical channel corresponding to the bearer is the data of the corresponding bearer of the benefit UE.

FIG. 6 is a second schematic diagram of a transmission protocol stack between a base station, a coordinated UE, and a benefit UE according to Embodiment 1 of the present invention. As shown in FIG. 6, the processing of the PDCP layer (including security and header compression) is performed between the base station and the benefit UE, and the coordinated UE does not participate in the PDCP layer processing, and the advantage is that the data of the benefit UE forwarded by the coordinated UE is encrypted and protected. The data, that is, the privacy of the benefiting UE, is not exposed to the cooperating UE. In addition, the processing of the RLC (including data buffering, segmentation, ARQ, etc.) is also performed between the base station and the benefiting UE, and the cooperative UE does not participate in the RLC layer processing, so that for the AM transmission mode, the ARQ reliability is determined by the base station and Benefit from UE support. In addition, since the coordinated UE cannot segment the data for the second time, the resource scheduling between the cooperative UE and the benefit UE needs to ensure that the size of the transport block is not changed. The cooperative UE participates in the MAC/PHY processing of the benefit UE data transmission according to the configuration of the base station (step 404 of FIG. 4), wherein the MAC/PHY transmission of the base station to the benefit UE is divided into two segments, and the hybrid automatic repeat request (Hybrid) Automatic Repeat reQuest (HARQ) transmission reliability is supported by the two segments of the HARQ process. For example, the downlink transport block first strives for reliable transmission to the cooperative UE, and strives for reliable transmission to the benefit UE. When the downlink data arrives at the coordinated UE from the base station, the coordinated UE needs to distinguish the downlink data from itself or the UE, and the coordinated UE distinguishes the data of the one bearer according to the configuration of the base station (step 404 in FIG. 4). Whether the receiver is its own or the UE. For example, the base station may be configured to associate the (partial) bearer of the benefiting UE with the partial bearer of the coordinated UE, and the downlink data received by the coordinated UE through the bearer or the logical channel corresponding to the bearer is the data of the corresponding bearer of the benefit UE.

FIG. 7 is a third schematic diagram of a transmission protocol stack between a base station, a coordinated UE, and a benefit UE according to Embodiment 1 of the present invention. As shown in FIG. 7, the processing of the PDCP layer (including security and header compression) is performed between the base station and the benefit UE, and the coordinated UE does not participate in the PDCP layer processing, and the advantage is that the data of the benefit UE forwarded by the coordinated UE is encrypted and protected. The data, that is, the privacy of the benefiting UE, is not exposed to the cooperating UE. In addition, the processing of the RLC (including data buffering, segmentation, ARQ, etc.) is also performed between the base station and the benefiting UE, and the cooperative UE does not participate in the RLC layer processing, so that for the AM transmission mode, the ARQ reliability is determined by the base station and Benefit from UE support. Since the coordinated UE cannot segment the data for the second time, the resource scheduling transmitted between the cooperative UE and the benefit UE needs to ensure that the size of the transport block is not changed. In addition, the main processing of the MAC layer (including HARQ, multiplexing, demultiplexing) is performed between the base station and the benefiting UE, wherein the transmission reliability of the base station to the benefiting UE is supported by the ARQ/HARQ process between the base station and the benefiting UE. The cooperative UE only participates in a few MAC layer scheduling processes, that is, receives the transport block of the benefit UE according to the downlink scheduling of the base station and forwards it to the benefit UE. The two transmission processes may be jointly scheduled or independently scheduled. The coordinated UE participates in the MAC/PHY processing of the benefit UE data transmission according to the configuration of the base station (step 404 of FIG. 4). When the downlink data arrives from the base station to the cooperative UE, the cooperative UE needs to distinguish the downlink data when it is itself, or To benefit the UE, the cooperative UE distinguishes whether the final receiver of the data of a certain bearer is itself or the UE, according to the configuration of the base station (step 404 of FIG. 4).
