Abstract: In response to a user equipment (UE) sending data to a first network side device over a first channel and to a second network side device over a second channel, a method includes determining that the first channel separately overlaps the second channel and a third channel. The method further includes allocating, according to priorities of the first channel and the second channel, a first transmit power to the first subframe j and a second transmit power to the second subframe i. The first transmit power is less than or equal to a first power upper limit. A sum of the first transmit power and the second transmit power is less than or equal to a first threshold. A sum of third transmit power of the third subframe i+1 and the first power upper limit is less than or equal to a preset second threshold.

Abstract: A method and apparatus for allocating and processing sequences in a communication system is disclosed. The method includes: dividing sequences in a sequence group into multiple sub-groups, each sub-group corresponding to its own mode of occupying time frequency resources; selecting sequences from a candidate sequence collection corresponding to each sub-group to form the sequences in the sub-group by: the sequences in a sub-group i in a sequence group k being composed of n sequences in the candidate sequence collection, the n sequences making a |ri/Ni−ck/Np1| or |(ri/Ni−ck/Np1) modu mk,i| function value the smallest, second smallest, till the nth smallest respectively; allocating the sequence group to cells, users or channels. It prevents the sequences highly correlated with the sequences of a specific length from appearing in other sequence groups, thus reducing interference, avoiding the trouble of storing the lists of massive sequence groups.

Abstract: Example control channel resource indication methods, user equipment, and network devices are described. One example method includes sending a preamble signal sequence by a user equipment. The user equipment receives higher layer signaling corresponding to the preamble signal sequence. The higher layer signaling is indicated by downlink control information carried in a common search space. A time-frequency resource detected by the user equipment when determining a control channel includes the common search space and user equipment-dedicated search space. The user equipment determines frequency domain resource location information of the user equipment-dedicated search space based on the higher layer signaling. The frequency domain resource location information includes a quantity of frequency domain resource units occupied by the user equipment-dedicated search space in frequency domain and a location of the frequency domain resource unit.
