Detailed Description
The embodiment of the invention can be applied to a 4G system, a 5G system or a new system generated in the future. The 4G system may be a Long Term Evolution (LTE) system, and the 5G system may be a New Radio (NR) system.
Fig. 1 illustrates an architecture of a communication system including an access network device and a terminal device.
A Terminal device, also called a Terminal, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc., is a device that provides voice and/or data connectivity to a User, for example, a handheld device, a vehicle-mounted device, etc. with a wireless connection function. Currently, some examples of terminals are: a Mobile phone (Mobile phone), a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable Device, a Virtual Reality (VR) Device, an Augmented Reality (AR) Device, a wireless terminal in Industrial Control (Industrial Control), a wireless terminal in unmanned driving (self driving), a wireless terminal in remote surgery (remote medical supply), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation safety, a wireless terminal in city (smart city), a wireless terminal in smart home (smart home), and the like.
The Access network device related in the embodiment of the present invention may also be referred to as a base station or AN Access Node (Access Node, abbreviated as AN) to provide a wireless Access service for the terminal. The Access Node may be a Base Transceiver Station (BTS) in a Global System for Mobile communication (GSM) System or a Code Division Multiple Access (CDMA) System, a Base Station (NodeB) in a Wideband Code Division Multiple Access (WCDMA) System, an evolved Node B (eNB or eNodeB) in an LTE System, a Transmission Reception Point (TRP) in a 5G network, a Base Station device (gNB), a small Base Station device, a wireless Access Node (WiFi AP), a wireless interworking Microwave Access Base Station (WiMAX BS), and the like, which are not limited in the present invention.
The plurality of the present invention means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. In addition, it should be understood that although the terms first, second, etc. may be used to describe various data in embodiments of the present invention, these data should not be limited by these terms. These terms are only used to distinguish the data from each other.
In a New Radio (NR) system for Fifth Generation (5G) mobile communication, a User Equipment (UE) and a Transmission Reception Point (TRP) are connected by establishing a Beam Pair (BPL). One TRP may correspond to a plurality of UEs by allocating beams to the plurality of UEs.
At present, when two UEs both need the same beam, to avoid collision, the TRP generally randomly allocates the Tx beam to one of the UEs, for example, in another communication system shown in fig. 2, taking an access network device as the TRP and a UE as a mobile phone as an example, specifically, two UEs (UE 1 and UE2) are correspondingly connected to the TRP, where a beam pair may be established between UE1 and the TRP through Tx beam 1 or Tx beam 2; a beam pair may be established between the UE2 and the TRP through the Tx beam 2 or the Tx beam 3, and when the Tx beam 2 is the best beam for both the UE1 and the UE2, if the Tx beam 2 is configured at the same time as one end of the BPL established between the UE1 and the UE2 and the TRP, interference between UEs may be generated. To avoid interference between UEs, TRP typically randomly selects to configure Tx beam 2 to UE2 and Tx beam 1 to UE 1; or Tx beam 2 to UE1 and Tx beam 3 to UE 2.
The above random allocation manner has no knowledge about the UE's own environment, for example, the energy of the alternative beams (Tx beam 1 and Tx beam 2) of the UE1 is better than the energy of the alternative beams (Tx beam 2 and Tx beam 3) of the UE2, and directly selecting one of the UE1 and the UE2 to occupy the Tx beam 2 at random may reduce the effective utilization rate of resources, which is not favorable for data transmission between the TRP and the UE, and especially, in case that the TRP is connected with more UEs, the overall peak speed may be affected.
Based on this, embodiments of the present invention provide a beam allocation method and apparatus, so as to solve the problem that the effective utilization rate of beam resources is reduced in a random allocation manner in the prior art. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
For the convenience of understanding the present embodiment, a detailed description will be given to a beam allocation method disclosed in the present embodiment.
Referring to fig. 3, an embodiment of the present invention provides a flow chart diagram of a beam allocation method, where the method includes:
step S301, obtaining beam configuration information of N UEs, where the beam configuration information includes an available beam number corresponding to each UE in the N UEs and receiving power information corresponding to each of the N UEs, where the receiving power information corresponding to a first UE includes receiving power of the first UE under each available beam, and the first UE is any one of the N UEs.
In specific implementation, the beam configuration Information of the UE may be obtained from Uplink Control Information (UCI) reported by the UE.
Step S302, when determining that the available beams respectively corresponding to K UEs in the N UEs all include the first available beam, allocating beams for the K UEs according to the available beam number respectively corresponding to the K UEs and/or the receiving power information respectively corresponding to the K UEs.
Wherein, N is a positive integer greater than 1, K is a positive integer greater than 1 and less than or equal to N, and the first available beam is an available beam with the largest received power among available beams corresponding to the UE. The UE herein refers to any UE of the N UEs, that is, there is one available beam with the largest received power for each UE, that is, there is one first available beam.
In the embodiment of the invention, when the available wave beams with the maximum receiving power respectively corresponding to K pieces of UE in N pieces of user equipment UE are determined to be the same wave beam, the wave beams are distributed to the K pieces of UE according to the number of the available wave beams respectively corresponding to the K pieces of UE and/or the receiving power information respectively corresponding to the K pieces of UE. Compared with a random allocation mode, the method has the advantages that the consideration on the number of the usable beams of the UE and/or the power of the usable beams is added, the effective utilization rate of beam resources can be improved, the data transmission between the TRP and the multiple UEs is facilitated, and therefore the integral peak speed is improved.
Further, in an optional implementation manner, the allocating beams to the K UEs according to the number of available beams corresponding to the K UEs respectively and/or the received power information corresponding to the K UEs respectively may be implemented as follows:
and allocating the first available beam to a second UE with the first number of available beams, wherein the first number is the minimum number of available beams in the number of available beams corresponding to the K UEs respectively.
In this embodiment, the available beam with the maximum receiving power corresponding to the K UEs, that is, the first available beam, is allocated to the second UE with the minimum number of available beams in the K UEs, so that it can be ensured that the UE with the small number of available beams preferentially obtains the beam and TRP communication, and the beam resource is effectively utilized for data transmission.
In specific implementation, if the UEs with the first number of available beams among the K UEs only include the second UE, the first available beam is allocated to the second UE; and if the number of the available beams corresponding to the M UEs in the K UEs is determined to be the first number, allocating the first available beam to a second UE in the M UEs according to the receiving power information corresponding to the M UEs respectively, wherein M is a positive integer which is greater than 1 and less than or equal to K.
Further, in an optional implementation manner, the allocating the first available beam to the second UE of the M UEs according to the received power information corresponding to the M UEs respectively includes:
when the receiving powers of the M UEs under the first available beam are different, the first available beam is distributed to a second UE with the minimum receiving power under the first available beam in the M UEs; alternatively, the first and second electrodes may be,
determining that the receiving power of Q UEs in the M UEs under the first available beam is first receiving power, the first receiving power is the minimum receiving power of the M UEs under the first available beam, allocating the first available beam to a second UE of the Q UEs, and the receiving power of the second UE under the second available beam of the second UE is smaller than the receiving power of any UE except the second U of the Q UEs under the second available beam; the second available beam of one UE is an available beam corresponding to the UE and having the largest received power except the first available beam, and Q is a positive integer greater than 1 and less than or equal to M.
In specific implementation, when the beam configuration information of the N UEs is obtained, for any one UE of the N UEs, the available beams corresponding to any one UE may be sorted from large to small according to the received power of the UE on each available beam corresponding to the UE.
Based on this, when it is determined that the available beams with the largest receiving power corresponding to K UEs in the N UEs are all the first available beams, and the number of the available beams corresponding to M UEs in the K UEs is all the first number, if it is determined that the receiving powers of the M UEs respectively under the 1 st-bit-ordered available beams (i.e., the first available beam) respectively corresponding to the M UEs are different, the first available beam is allocated to the second UE with the smallest receiving power under the first available beam among the M UEs; if the reception power of Q UEs in the M UEs under the first available wave beam is judged to be the first reception power, the Q UEs under the respectively corresponding available wave beams with the sequencing 2 nd bit are continuously judged to be different, the first available wave beam is distributed to a second UE in the Q UEs, and the reception power of the second UE under the corresponding available wave beam with the sequencing 2 nd bit is the minimum reception power of the Q UEs under the respectively corresponding available wave beams with the sequencing 2 nd bit; or when the receiving power of the H UEs in the Q UEs under the respectively corresponding ranking 2 nd available beam is judged to be the minimum receiving power of the Q UEs under the respectively corresponding ranking 2 nd available beam, the receiving power of the H UEs under the respectively corresponding ranking 3 rd available beam is continuously compared, and so on, to determine to specifically allocate the first available beam to one UE.
For convenience of implementation, the embodiment of the present invention takes two UEs out of M UEs, that is, the fourth UE and the fifth UE respectively have the minimum receiving power under the first available beam, and the method for allocating the first available beam to the second UE with the minimum receiving power under the available beam with the maximum receiving power except the first available beam among the Q UEs is described in detail as follows:
when the receiving power of the fourth UE and the receiving power of the fifth UE under the first available beam in the M UEs are all determined to be minimum, sequentially and circularly executing:
judging that the receiving power of a second available beam corresponding to the fourth UE is the same as the receiving power of a third available beam corresponding to the fifth UE, taking the (i + 1) th available beam in the available beam corresponding to the fourth UE as the second available beam, and taking the (i + 1) th available beam in the available beam corresponding to the fifth UE as the third available beam;
the second available beam is an available beam located at the ith position in the available beams corresponding to the fourth UE in descending order of received power, and the third available beam is an available beam located at the ith position in the available beams corresponding to the fifth UE in descending order of received power; i sequentially taking positive integers from 2 to the first number;
allocating the first available beam to the fourth UE when it is determined that the received power of the second available beam is less than the received power of the third available beam; alternatively, the first available beam is allocated to the fifth UE when it is determined that the reception power of the third available beam is less than the reception power of the second available beam.
In addition, if the received power of the second available beam is still equal to the received power of the third available beam when i takes the value of the first number, the foregoing cycle is stopped, and further in an optional embodiment, the first available beam is randomly allocated to the fourth UE or the fifth UE; in another optional embodiment, the first available beam may be determined to be allocated to the fourth UE or the fifth UE according to a preconfigured UE service priority, for example, the fourth UE currently needs to perform live broadcast, the fifth UE currently needs to perform voice call, and the first available beam is allocated to the fourth UE when the preconfigured UE service priority is higher. Of course, it should be noted that this is only one example. In specific implementation, the UE service priority may be set according to an actual situation, and is not limited herein.
In the embodiment of the invention, when the number of the available beams of the Q UEs in the K UEs is the first number, that is, the smallest number, the first available beam is determined to be allocated to the second UE in the Q UEs according to the size of the receiving power of the available beams at the same ranking position in the available beams corresponding to the Q UEs respectively, so that when the number of the available beams of the multiple UEs is the same and the smallest number, the beam is preferentially allocated to the UE with the smaller receiving power under the available beams ranked equally in the available beams corresponding to the multiple UEs, and the marginal UE, that is, the UE with the smaller available beams and the lower energy, preferentially obtains the allocation of the beams, thereby better realizing the data transmission between the UE and the TRP and improving the overall peak speed.
Further, after the method determines to allocate the first available beam to the second UE, in an alternative embodiment, the first available beam may be deleted from the available beams corresponding to the N UEs, then, for the remaining N-1 UEs without allocated beams, the best selected beam of each UE, that is, the first available beam, is re-determined, and then, according to the above manner, the re-determined first available beam is allocated to one of the N-1 UEs, and so on until the N UEs all obtain a beam paired with the TRP, so that data transmission between the TRP and the N UEs is ensured.
Further, for convenience of implementation, another beam allocation method is further provided in an embodiment of the present invention, where it is assumed that a base station (gNB) in the 5G NR system needs to establish a BPL with N User Equipments (UEs), each UE of the N UEs corresponds to multiple available Tx beams, and each UE receives UCI information reported by the N UEs by carrying the number of the available beams and the Receiving Power of each available beam, such as Reference Signal Receiving Power (RSRP), in the UCI information reported by the base station, and allocates beams to the N UEs according to the UCI information reported by the N UEs. For the convenience of understanding, the plurality of UEs are referred to as N UEs, N represents the number of the UEs, N is more than or equal to 1 and less than or equal to N, and the number of the available beams of the nth UE is Ln。
